32936VB061 Single‑Row Tapered Roller Bearing 180×250×45mm For Excavator Construction Machinery

The 32936VB061 is a single‑row open tapered roller bearing, designed for heavy‑duty construction and mining machinery assemblies. It is separable construction with cone and cup, capable of bearing large combined radial and unidirectional axial loads under shock‑prone harsh working conditions.
It is widely used for excavator, mining and heavy engineering equipment where high mixed‑load capacity is required.

• High combined radial‑axial load capacity for heavy‑duty construction‑machinery applications
• Separable cone‑and‑cup structure for convenient mounting, dismounting and preload adjustment
• Optimized roller geometry for low‑heat generation and stable running under impact load
• Excellent shock‑resistance performance for dusty mining and excavator working conditions
• Suitable for excavator, mining machinery and heavy‑duty rotary transmission assemblies
• Custom design available (clearance grade, OEM laser marking)

This bearing is widely used in:

• Excavator swing and travel drive assemblies
• Mining machinery heavy‑load rotary support parts
• Heavy‑duty construction equipment transmission units
• Metallurgical plant auxiliary rotating mechanisms
• Engineering‑machinery aftermarket replacement projects

• 25+ years experience in industrial bearing manufacturing
• Exported to 50+ countries worldwide
• Rich experience in OEM & custom projects
• Strict quality inspection before shipment
• Fast response within 24 hours
• Stable supply for long‑term cooperation

• Raw material chemical composition & hardness inspection
• Precision turning and raceway mirror‑superfinishing machining
• Heat treatment process control for stable internal stress
• Clearance, contact pattern & rotational flexibility testing
• Final visual & dimensional inspection before delivery
